Operating manual V2.0
The lift controller sets itself a car call to any other floor. At trip end the brake / valve
monitoring input is ignored by the lift controller. Depending on the defined monitoring time the
lift controller goes out of operation.

6.1.8 Testing the contactor monitoring (Contactor drop off control)

The lift must be in normal operation. For testing, the menu item "Technical check"->" Runn.
contactor " must be started.
Here must be entered first, which relay of the HSE should not be switched off at trip end. The
selection is made by pressing a numeric key like shown in the table below:
Numeric key
Only the numeric keys are accepted, where the appropiate relay is programmed as a drive
output relay (output function "Drive").
After defining the relay number the lift controller sets at random car call to another floor. At
the end of the trip to this floor the corresponding HSE relay is not switched off. Within the
LCD display the current floor and the control condition are displayed.
By pressing the ESC key, the HSE relay is switched off and the test is ended.

6.1.9 Uncontrolled movement

For testing the lift behavior by uncrontrolled movement the lift controller starts a trip in
upward or downward direction (like selected).
The LCD display shows the actual floor, actual position and difference to floor level (and with
this the distance the cabin moves away from floor level until the UCM device stops the lift).
This test is only possible if the UCM protection is done by the lift controller. If a UCM system
from another manufacturer is used the test must be done according to that documentation.
For more details please refer to the TUEV certificate of the lift controller.
Up to HSE software version 1.38p this test is done for roped lifts by just opening the
motor brake. The lift will move than, depending of the load, in up or down direction
away from level zone. Starting with HSE software version 1.38q the lift is moving by
motor force out of door zone into the selected direction.
